STORMWATER MANAGEMENT SYSTEM DESIGN AND ANALYSIS FOR
HAWKINS EAST DISPOSAL AREA
PURPOSE
The purpose of this calculation package is to establish the design criteria, analysis
methodology, and design parameters and to present computations and results for a
stormwater management system to control runoff from the Spruce Pine Rock and Tailings
Hawkins East Disposal Area(Hawkins East Disposal Area). Specifically,this calculation
package presents the hydrologic and hydraulic calculations conducted to support the
design of the stormwater management system conveying runoff to the sediment basin
located south of the Hawkins East Disposal Area. Stormwater runoff flows down the
2H:1 V (horizontal:vertical) side slopes of the final cover system through periodically
spaced conveyances including side slope drainage terraces, down drain pipes, and
drainage channels.
The remainder of this calculation package is organized to present: (i)design and analysis
methodology; (ii)design parameters; (iii) design criteria, computations, and results; (iv)
summary and conclusions; and (v) references for the stormwater management system
associated with the Hawkins East Disposal Area.
DESIGN AND ANALYSIS METHODOLOGY
The stormwater management system, as presented in the Spruce Pine Rock and Tailings
Disposal Areas Permit Drawings for Hawkins East dated 3 July 2024 [Geosyntec,2024],
was designed to meet criteria identified from the following documents as well as design
considerations based on general engineering practices from industry technical literature:
• National Pollutant Discharge Elimination System (NPDES) General Permit No.
NCGO10000 for Construction Activities that are also Subject to the North
Carolina Sedimentation Pollution Control Act of 1973 [NCDEQ,2019];
• NPDES General Permit No. NCG020000 for Active and Inactive Mining Sites
[NCDEQ,2021];
• North Carolina Department of Environmental Quality (NCDEQ) Erosion and
Sediment Control Planning and Design Manual (Erosion and Sediment Control
Manual) [NCDEQ, 2013]; and
• NCDEQ Stormwater Design Manual (NCDEQ Manual) [NCDEQ,2017].

Specific design criteria and computations for each stormwater management system
component are described in detail below. Stormwater flow rates, depths, and volumes
were calculated using hydrology and hydraulic procedures presented in the Soil
Conservation Service (SCS) Technical Release 55 (TR-55), Manning's kinematic
equation, and other recognized engineering procedures encoded in HydroCADTM
software [SCS, 1986; HydroCADTM, 2023]. Stormwater pipes were designed using HY-
8,which was developed by the Federal Highway Administration(FHWA)to computerize
the implementation of FHWA-endorsed culvert hydraulic analysis approaches and
protocols [FHWA,2006 and 2012].
DESIGN PARAMETERS
• Rainfall Distribution and Depths: Figure 1 [SCS, 1986]shows the location of the
Hawkins East Disposal Area on the rainfall distribution map of the United States.
The Hawkins East Disposal Area is located in Mitchell County, North Carolina,
which is characterized as having a Type II Rainfall Distribution. Rainfall depths
for the design storm events and for calculating times of concentration (TOC)are:
(i)4.01 inches(in.)for the 2-year(yr),24-hour(hr)storm; (ii) 5.98 in.for the 10-
yr, 24-hr storm; (iii) 7.23 in. for the 25-yr, 24-hr storm; and (iii) 9.37 in. for the
100-yr,24-hr storm[National Oceanic and Atmospheric Administration(NOAA),
2017], as shown in Attachment 1. Analysis for the stormwater management
system was performed for the 10-yr,24-hr;25-yr,24-hr;and 100-yr,24-hr design
storm events. TOC calculations utilize the 2-yr,24-hr design storm event.
• Drainage Areas: Figure 2 presents the approximate drainage area delineations for
final conditions at the Hawkins East Disposal Area. Drainage areas were
delineated to represent areas discharging to the side slope drainage terraces,down
drain pipes, and drainage channels which convey stormwater runoff to the
sediment basin.Table 1 presents the acreages of the delineated drainage areas.
• Hydrologic Soil Groups:Hydrologic Soil Group(HSG)D was used in the analysis
since areas associated with land disturbing activities will be compacted during
construction.
• Curve Numbers: The curve numbers (CNs)for the drainage areas contributing to
the stormwater management system are shown in Table 1. The CNs
corresponding to the land cover and HSG were selected based on Table 2-2 of
GC9914/SWMS Design And Analysis For Hawkins East Disposal Area Rev 1

TR-55 [SCS, 1986] and interpretations within the HydroCADTM Manual
[HydroCADT", 2023]. The following table summarizes the CNs chosen for the
analyses performed in this calculation package.

Grassed Areas Fair Condition(Grass Cover D 84

Water Surfaces Impervious Area - 98
• Times of Concentration: Table 2 presents the characteristics of the flow paths
used to calculate the TOCs for the drainage areas. Computations for travel time
for sheet flow are performed using the equation for Manning's kinematic solution
[SCS, 1986]:
0.007(nL)0•8 Tt — po.sSo.4 (1)
where: Tt=travel time (hr); n =Manning's roughness coefficient(unitless); L =
flow length (feet, ft); P =2-yr, 24-hr rainfall depth (in.); and S = land slope (feet
per feet, ft/ft).
After a maximum of 100 ft,sheet flow is assumed to become shallow concentrated
flow (i.e., upland flow). Travel times for shallow concentrated flow were
estimated from SCS TR-55 [SCS, 1986] as follows:
_ L
Tt 3600V (2)
V = KSo.s (3)
where: Tt = travel time (hr); L = flow length (ft); V = average velocity (feet per
second, ft/s);K=velocity factor(ft/s); and S =land slope(ft/ft).
A minimum TOC of 6 minutes was selected for drainage areas where the
calculated TOC was less than 6 minutes, based on recommendations from SCS
[SCS, 1986].

DESIGN CRITERIA,COMPUTATIONS AND RESULTS FOR THE DESIGN
OF THE STORMWATER MANAGEMENT SYSTEM
HydroCADTM was used to analyze the stormwater management system conditions using
the input parameters discussed in the previous section for the 10-yr, 24-hr; 25-yr, 24-hr;
and 100-yr, 24-hr design storm events; results are presented in Attachment 2. Non-
principal spillway pipe segments were designed using HY-8; results are presented in
Attachment 3. The design criteria, methodology, computations, and results for the
stormwater management system components are discussed in detail below.
Side Slope Drainage Terraces, Access Road Drainage Channels, and Perimeter
Channels
Side slope drainage terraces and access road drainage channels convey stormwater from
the final cover system to the perimeter channels located along the perimeter of the
Hawkins East Disposal Area.The perimeter channels,in addition to the perimeter channel
pipe, convey stormwater runoff to the sediment basin located south of the Hawkins East
Disposal Area. The locations of the side slope drainage terraces, access road drainage
channels, and perimeter channels are depicted on Figure 2, while Table 3 presents the
characteristics of these conveyance features.
The side slope drainage terraces, access road drainage channels, and perimeter channels
were designed as follows:
• The side slope drainage terraces were designed as vee-shaped channels with
5H:1 V side slopes intersecting the 2H:1 V side slopes of the final cover system,
minimum depths of 3.0 ft, and longitudinal slopes ranging from 0.010 to 0.044
ft/ft.
• The access road drainage channels were designed as trapezoidal-shaped channels
with 2H:1 V side slopes, bottom widths of 7.0 ft, minimum depths of 3.0 ft, and
longitudinal slopes ranging from 0.079 to 0.080 ft/ft.
• The perimeter channels were designed as trapezoidal-shaped channels with
3H:1 V side slopes, bottom widths of 15.0 ft or 17.5 ft,minimum depths of 3.0 ft,
and longitudinal slopes ranging from 0.109 to 0.211 ft/ft.

Client: Sibelco Project: Spruce Pine Rock and Tailings Disposal Areas Project No: GC9914
The hydraulic capacities of the side slope drainage terraces, access road drainage
channels,and perimeter channels were also evaluated using accepted engineering practice
and guidance for stormwater conveyance channels in the NCDEQ Erosion and Sediment
Control Manual [NCDEQ, 2013]. Following general engineering practice, side slope
drainage terraces, access road drainage channels, and perimeter channels were designed
to convey the 10-yr,24-hr design storm event with 0.5 ft of freeboard and convey the 25-
yr,24-hr design storm event without overtopping.
Table 4 presents the hydraulic calculations for side slope drainage terraces, access road
drainage channels, and perimeter channels. The calculated freeboard depths are greater
than 0.5 ft for the 10-yr, 24-hr design storm event and the peak flow depths are contained
without overtopping for the 25-yr, 24-hr design storm event.
Side Slope Drainage Terraces, Access Road Drainage Channels, and Perimeter
Channels Lining
Side slope drainage terraces,access road drainage channels,and perimeter channels were
designed with riprap lining in accordance with the NCDEQ Erosion and Sediment
Control Manual [NCDEQ, 2013].
Riprap gradations for side slope drainage terraces, access road drainage channels, and
perimeter channels were selected or extrapolated from Table 8.05g of the NCDEQ
Erosion and Sediment Control Manual [NCDEQ,2013]using the tractive force procedure
for permissible shear stress outlined in Section 8.05.1 of the NCDEQ Erosion and
Sediment Control Manual [NCDEQ,2013]. Side slope drainage terraces and access road
drainage channels were designed with dso values of 9.0 in. and 18.0 in., respectively.
Perimeter channels were designed with dso values of 15.0 in, 21.0 in., 27.0 in., and 30.0
in.
The selected d50 value was then used in the following equation to calculate the Manning's
roughness coefficient associated with each riprap size:
n = 0.0395(dso)1/6 (4)
where: n=Manning's roughness coefficient for stone riprap and dso=diameter of stone
for which 50%, by weight, of the gradation is finer(ft) [USGS, 1986].

CP: SH Date: 7/3/24 APC: KM Date: 7/3/24 CC: KM Date: 7/3/24
Client: Sibelco Project: Spruce Pine Rock and Tailings Disposal Areas Project No: GC9914
Shear stress was estimated using the following equation from Section 8.05.1 of the
NCDEQ Erosion and Sediment Control Manual [NCDEQ, 20131:
T = yds (5)
where: T = shear stress (pounds per square foot, lb/ft); y = unit weight of water (62.4
lb/ftz); d=flow depth(ft); and s=channel slope(ft/ft).
Riprap gradation was considered acceptable if the permissible shear stress, Td, provided
in Table 8.05g of the NCDEQ Erosion and Sediment Control Manual [NCDEQ, 2013]
exceeded the calculated shear stress.
The channel lining thickness was designed as 1.5 times the d..of the assigned gradation.
Results of the channel lining analysis are presented in Table 5 for side slope drainage
terraces, access road drainage channels,and perimeter channels.
Stormwater Pipes
Down drain pipes convey stormwater from the side slope drainage terraces to the access
road drainage channels and perimeter channels,while the perimeter channel pipe conveys
stormwater under the access road.The sediment basin pipe conveys stormwater from the
sediment basin outlet structure to the discharge location. The locations of these pipes are
depicted on Figure 2, while Table 6 presents the characteristics of these conveyance
features. The sizing of a representative down drain pipe was evaluated based on the
largest contributing drainage area to the stormwater feature.
These pipes were designed and analyzed to safely convey the 25-yr, 24-hr design storm
event without overtopping. The overtopping elevation is typically defined as the lowest
elevation that would overtop surrounding roads, berms, or channel banks. When the
upstream end of a pipe was located within a stormwater channel, the overtopping
elevation was considered to be the elevation of the- access road adjacent to or
downgradient of the channel at the location of the pipe. When the upstream end of a pipe
was located within the sediment basin outlet structure, the overtopping elevation was
considered to be the sediment basin embankment elevation.
Table 6 presents the characteristics and analysis of pipes for hydraulic capacity for the
25-yr,24-hr design storm event. The pipes were designed as single or multiple barrels of

corrugated high density polyethylene pipe (HDPE) or reinforced concrete pipe (RCP)
with Manning's n values of 0.012 [FHWA, 2012].
Using Figure 5-28 of the United States Army Corps of Engineers (USACE) Conduits,
Pipes, and Culverts Associated with Dams and Levee Systems Manual [USACE, 2020],
a filter diaphragm was designed for the perimeter channel pipe to reduce the risk of
seepage or"piping" along the outer wall of the pipe. The filter diaphragm was designed
with a width equivalent to the four conduits with spacing between each parallel pipe equal
to one-half the pipe diameter and 4 ft on the exterior side of the outermost two pipes, a
height of 4 ft above and below the pipes, and a thickness of 3 ft.
Sediment Basin
The sediment basin was designed using guidance from the NCDEQ Erosion and Sediment
Control Manual [NCDEQ, 2013] and general engineering practices. The stage-storage
relationship for the sediment basin is provided in Table 7. Table 8 presents a summary
of the design details and outlet structures for the sediment basin and includes the peak
water depths and discharge flow rates for the 10-yr, 24-hr; 25-yr, 24-hr; and 100-yr, 24-
hr design storm events.
Specific design criteria were developed and met as follows:
• Volume: Section 6.61 of the NCDEQ Erosion and Sediment Control Manual
[NCDEQ,20131 requires,at a minimum, 1 ft of freeboard between the peak water
surface elevation of the 10-yr, 24-hr design storm event and the top of the settled
embankment.The sediment basin was designed with a minimum 1 ft of freeboard
for the 100-yr,24-hr design storm event.
• Outlet Structure:
o Principal Spillway — Section 6.61 of the NCDEQ Erosion and Sediment
Control Manual [NCDEQ, 2013] requires the principal spillway to
convey, at a minimum, the peak runoff from the 2-yr, 24-hr design storm
event. The principal spillway was designed as a square concrete riser
structure with inner dimensions of 3 ft by 3 ft. The principal spillway
conveys the 25-yr, 24-hr design storm event with at least 1.6 ft of
freeboard between the peak water surface elevation and the invert of the
emergency spillway.

o Drawdown Orifice — The principal spillway was designed with a 6 in.
diameter circular orifice at the base of the riser structure to attach a floating
skimmer to control the rate of dewatering.
o Emergency Spillway—Section 6.61 of the NCDEQ Erosion and Sediment
Control Manual [NCDEQ, 2013] requires the emergency spillway to
convey,at a minimum,the peak runoff from the 10-yr,24-hr design storm
event with at least 1 ft of freeboard.The emergency spillway was designed
as a trapezoidal weird with a 25-ft wide bottom, 3H:1 V side slopes, and a
1.5 ft depth. The emergency spillway is not engaged during the 100-yr,
24-hr design storm event and therefore maintains at least 1 ft of freeboard
between the peak water surface elevation and the embankment.
• Filter Diaphragm—A filter diaphragm was designed for the sediment basin pipe
to reduce the risk of seepage or "piping" along the outer wall of the pipe in
accordance with Figure 5-28 of the United States Army Corps of Engineers
(USACE) Conduits, Pipes, and Culverts Associated with Dams and Levee
Systems Manual [USACE,2020].The filter diaphragm was designed with a width
equivalent to the pipe diameter and 4 ft on the exterior side of the pipe, a height
of 4 ft above and below the pipe, and a thickness of 3 ft. Filter diaphragm
dimensions for the sediment basin pipe are presented in Table 9.
• Riser Base Block— Section 6.61 of the NCDEQ Erosion and Sediment Control
Manual [NCDEQ,2013]requires the riser be secured by an anchor with a buoyant
weight greater than 1.1 times the water displaced by the riser. The concrete riser
base block was sized to prevent flotation of the principal spillway riser and pipe
by offsetting the buoyant forces of the riser and pipe using a factor of safety of
2.0. The factor of safety (FS)to prevent buoyancy was calculated as follows:
FS = Fa
(6)
where: Fa is the anchoring force (i.e., weight of the riser block) in pounds (lbs)
and Fb is the buoyancy force in lbs(i.e.,weight of water displaced by the riser and
spillway pipe, assuming the water surface elevation is at the principal spillway
riser crest).
The anchoring force, Fa, was calculated as:
Fa = (YcHR(WRLR — WrLr)) + (YcLBWBYB) (7)
where:7,is the specific weight of concrete(= 1501bs/ft); LR is the outside length
of the riser structure (ft); WR is the outside width of the riser structure (ft); Wr is

the inside width of the rider structure (ft); Lr is the inside length of the riser
structure(ft); HR is the height of the rider structure(ft); LB is the riser base length
(ft); WB is the riser base width (ft); and YB is the riser base thickness (ft).
The buoyancy force, Fb, was calculated as:
Fb = Yw 4(LPDP2) +YwLRWRH (8)
where: 'yw is the specific weight of water (= 62.4 lbs/ft); H is the height of the
spillway riser (ft) relative to the invert of the riser structure; LR is the outside
length of the spillway riser structure (ft); WR is the outside width of the spillway
riser structure (ft); Lp is the length of the exposed spillway pipe (i.e., not located
under the basin embankment or basin bottom); and Dp is the diameter of the
spillway pipe.
Table 10 presents the characteristics and calculations of the riser base for the
sediment basin. The riser base will be 6 ft wide by 6 ft long and 1.0 ft thick. The
calculated FS for the sediment basin is 2.0.
• Trash Guard—Section 6.61 of the NCDEQ Erosion and Sediment Control Manual
[NCDEQ, 2013] requires a trash guard to be installed on the top of the riser to
prevent trash and other debris from clogging the conduit.
SUMMARY AND CONCLUSIONS
The stormwater management system analyzed as part of this calculation package for the
Hawkins East Disposal Area located in Mitchell County,North Carolina consists of side
slope drainage terraces, access road drainage channels, and perimeter drainage channels
to convey runoff to the sediment basin.The stormwater management system,as presented
in the Spruce Pine Rock and Tailings Disposal Areas Permit Drawings for Hawkins East
dated 3 July 2024 [Geosyntec, 2024], was designed for the collection, conveyance, and
detention of flows from the 10-yr, 24-hr; 25-yr, 24-hr; and 100-yr, 24-hr design storm
events.The system was designed to meet criteria presented in the NCGO 10000 [NCDEQ,
2019], the NCG020000 [NCDEQ, 2021], the NCDEQ Erosion and Sediment Control
Manual [NCDEQ, 2013], the NCDEQ Stormwater Design Manual [NCDEQ,2017], and
general engineering practices.
The stormwater management system also requires the design and analysis of supporting
components, such as filter diaphragms, riser structures, and anchor blocks. These

supporting components were designed with the appropriate factors of safety or to meet
minimum or maximum velocities or storage volumes, as appropriate. Based on the
calculations, the design of side slope drainage terraces, access road drainage channels,
perimeter drainage channels, stormwater pipes, and sediment basin provide the required
capacity and factors of safety to comply with the design criteria.

[Numbers
Precipitation frequency(PF)estimetas In this table are based on frequency analysis of partial duration series(PDS).
in parenthesis ere PF estimates at lower and upper bounds of the 90%confidenceinterval.The probability that precipitation frequency estimates
or a given duration and average recurrence interval)vdll be greater than the upper bound(or less then the lower bound)is 5%.Estimates at upper bounds
re not checked against probable maximum precipitation(PMP)estimates and may be higher titan currently valid PMP values.
